Verdict

The call

The clearest difference is rating: my NOS at 4.2 against DUApp's 1.8. my NOS also leads on ratings volume (283 vs 4) and review sentiment (13% vs 0%). DUApp's advantage is ads (none vs shown) and monetization model (free vs ad-supported). On price, in-app purchases, device support and iOS requirement there is nothing between them.
